 p. 105. 



Hab. Andes, from New Granada southward to Peru. — Mettenius admits our three 

 varieties as species, and also_ /. scalaris, Kze., and /. rotundifolia, Fie, the latter a 

 robust plant, most like y, but with closer and rounder pinnae. 



Gen. 50. NoxiiocHLyENA, li. Br, (See page 514.) 



Sori marginal, at first oblong or roundish, soon confluent into a continuous 

 marginal line, without a distinct involucre, but with the edge of the frond fre- 

 quently inflexed. Veins free in all the species. A small widely-dispersed genus, 

 differing from Cheilanthes only by the absence of a distinct involucre, and connected 

 with it by gradual intermediate stages. Tab. 6. /. 60.

 pressed, linear, black in the centre and ferruginous towards the edge ; st. 8-4 

 in. 1., wiry, erect, naked, dark chesnut-brown ; fr. 6-9 in. 1., \ in. br., simply 

 pinnate ; pinnce in distant pairs, nearly as broad as long, deeply pinnatifid ; 

 texture subcoriaceous ; upper surface pale-green, naked, lower densely matted 

 with ferruginous tomentum ; sori black, the edge not inflexed.— i/^. Sp. 5. 

 p. 110. 



Hab. Namaqua land, Eev. Mr, Whitehead. 



2. N. sinuata, Kaulf. ; rhizome very thick, densely clothed with linear briglit 

 ferruginous scales and bearing bulbs ; st. subtufted, 2-4 in. 1., firm, erect, chesnut- 

 brown, matted ^fr. 1-2 ft. 1., 1-2 in. br., simply pinnate ; pinnce short-stalked, ^-1 

 in. 1., |-^ in. br., ovate or oblong, varying from entire to deeply pinnatifid ; texture 

 thick, coriaceous ; upper surface green and slightly villose ; lower surface and

 —Hk. Sp. 5. p. 108, Bot. Mag. t. 4699. 



Hab. New Mexico, along the Andes to Chili.

 slightly matted ; fr. 6-12 in. 1., ^-1 in. br., simply pinnate ; pinnce sessile, \-\ 

 in. 1., ovate, deeply pinnatifid, with blunt lobes ; texture coriaceous ; upper surface 

 pale-green, villose, lower densely matted with ferruginous or nearly white tomen- 

 tum ; edge inflexed, slightly membranous ; sori black. — Hk. Sp. 5. p. 108. 2nd 

 Cent. t. 62. 



Hab. West Indies and Mexico, along the Andes to Chili. — This and the two preceding 

 may be distinguished from the rest of the group by having even the lower pinnae pinnatifid 

 only.

 in. 1., \-\\ in. br., oblong-lanceolate, bipinnate ; pinnce close, lanceolate, the 

 central ones the largest, with close, roundish or oblong, entire or 8-lobed pinnl. ; 

 texture herbaceous but thick ; both sides, especially the lower one, coated with 

 whitish or subferruginoiis tomentum ; rachis briglit chesnut-brown, more or less 

 woolly. — Hk. Sp. 5. p. 11 9. 



Hab. South Europe, from Spain to Syria, Greece, Madeira, TenerifFe, Cape Verde
